Fertilo in vitro forskningsundersøgelse og prøve (FIRST)

6. oktober 2026 opdateret af: Gameto, Inc.

Fase III Randomiseret kontrolforsøg for at undersøge sikkerheden og effektiviteten af ​​gødning versus medicid in vitro modning (IVM)

The goal of this clinical trial is to evaluate the safety and efficacy of using Fertilo for In vitro maturation (IVM) in participants 18-35 years of age. The main question it aims to answer is whether the use of Fertilo is superior to using Medicult IVM for In vitro maturation.

Researchers will compare the number of ongoing pregnancies at 12 weeks gestation for participants in each arm.

  • Arm 1 participants will have all cumulus oocyte complexes (COCs), or eggs surrounded by helper cells, cultured in Fertilo for 30 hours.
  • Arm 2 participants will have all cumulus oocyte complexes (COCs), or eggs surrounded by helper cells, cultured in Medicult IVM for 30 hours.

Deltagergruppe / Arm
Intervention / Behandling
Eksperimentel: Fertilo

Immature cumulus-oocyte complexes (COCs) are oocytes surrounded by cumulus cells that have not yet matured. The COCs are cultured in Fertilo coculture condition then fertilized, grown to the blastocyst stage, vitrified, and later transferred for reproductive purpose.

Fertilo is an engineered line of ovarian support cells that aid egg maturation.

Aktiv komparator: Medicult IVM®

Immature COCs are cultured in the standard IVM system MediCult IVM® then fertilized, grown to the blastocyst stage, vitrified, and later transferred for reproductive purpose.

MediCult IVM is a system of culture media designed for the in vitro maturation of immature oocytes.

Foranstaltningsbeskrivelse
Tidsramme
Demonstration of the superiority of Fertilo compared to the currently approved MediCult IVM® for infertility treatment via IVF procedures.
Tidsramme: 12 weeks gestation

Cumulative ongoing pregnancy from cycles initiated within 6 months post-randomization. The primary endpoint of ongoing pregnancy is assessed at 12 weeks gestation or later. Cumulative ongoing pregnancy is determined using the cumulative outcome of up to the first two embryo transfers. Subjects with a detectable fetal heartbeat, considered normal and healthy, are considered as having achieved an ongoing pregnancy. "Normal" will be determined as expected for the gestational age ranging from 110 bpm to 180 bpm and measured via ultrasound. Ongoing pregnancy is recorded as either a Yes or No for normal fetal heart rate present for each of the Subject's transfer cycles. Subjects without an ongoing pregnancy assessment are considered as a No unless a later observation indicates otherwise (i.e., a live birth). Cumulative ongoing pregnancy is derived as either a Yes, if at least one of the first two embryo transfers achieves an ongoing pregnancy, or a No otherwise.

Foranstaltningsbeskrivelse
Tidsramme
Metaphase II (MII) Formation
Tidsramme: 30 hours post-oocyte retrieval

MII formation rate is assessed at 30 hours post-oocyte retrieval. A Metaphase II (MII) oocyte is defined as an oocyte with a first polar body (PB1). The MII formation rate is measured as a Subject's total number of MII oocytes divided by their total number of COCs. The MII formation rate is multiplied by 100 and expressed as a percentage.

30 hours post-oocyte retrieval
Fertilization Rate
Tidsramme: 16-18 hours post-ICSI

Fertilization rate is assessed at 16-18 hours post-ICSI. Fertilized embryos displaying 2 pronuclei and 2 polar bodies are considered normally fertilized. Fertilized embryos with no pronuclei are considered not fertilized. Fertilized embryos with one pronuclei are held to determine cleavage, as pronuclei visualization timing may mask the second pronucleus. The fertilization rate is measured as a Subject's total number of fertilized embryos divided by their total number of COCs. The fertilization rate is multiplied by 100 and expressed as a percentage.

16-18 hours post-ICSI
Embryo cleavage rate
Tidsramme: Day 3 post-ICSI

Embryo cleavage rate is assessed at day 3 post-ICSI. Embryos with 2 or more cells are considered as cleaved. Fertilized embryos displaying a single cell will be considered not cleaved. The cell cleavage rate is measured as a Subject's total number of embryos considered as cleaved divided by their total number of COCs. The cell cleavage rate is multiplied by 100 and expressed as a percentage.

Day 3 post-ICSI
High quality blastocyst formation rate.
Tidsramme: Day 5, 6, and 7 post-ICSI

High quality blastocyst formation rate is assessed at day 5, 6 and 7 post-ICSI. Embryos that have successfully passed the morula stage, as indicated by cavitation, will be designated as blastocysts and will be graded according to the Gardner Scale. Blastocysts having a Gardner Scale score of 3CC or higher are considered as high quality blastocysts. The high quality blastocyst formation rate is measured as a Subject's total number of high quality blastocysts divided by their total number of COCs. The high quality blastocyst formation rate is multiplied by 100 and expressed as a percentage.

Day 5, 6, and 7 post-ICSI
High quality vitrified blastocyst rate.
Tidsramme: Day 5, 6, and 7 post-ICSI

High quality vitrified blastocyst rate is assessed at day 5, 6 and 7 post-ICSI. Embryos deemed high quality, as measured by a Gardner score of 3CC of greater, that have been vitrified, a method of rapid cryopreservation for future embryo transfer, will be designated as high quality vitrified blastocysts. The high quality vitrified blastocyst rate is measured as a Subject's total number of high quality blastocysts that are vitrified divided by their total number of COCs. The high quality vitrified blastocyst rate is multiplied by 100 and expressed as a percentage.

Day 5, 6, and 7 post-ICSI
Cumulative biochemical pregnancy.
Tidsramme: 10 to 14 days following FET

Cumulative biochemical pregnancy from cycles initiated within 6 months post randomization. Biochemical pregnancy is assessed at 10 to 14 days following FET. Cumulative biochemical pregnancy is determined using the cumulative outcome of up to the first two embryo transfers. Subjects with BHCG value greater than 5 mIU/mL on two separate tests are considered as achieving biochemical pregnancy. Biochemical pregnancy is recorded as either a Yes or No for each of the Subject's transfer cycles. Subjects without a biochemical pregnancy assessment are considered as a No unless a later observation indicates otherwise (i.e., a clinical pregnancy, ongoing pregnancy, or live birth). Cumulative biochemical pregnancy is derived as either a Yes, if at least one of the first two embryo transfers achieves a biochemical pregnancy, or a No otherwise.

10 to 14 days following FET
Cumulative clinical pregnancy.
Tidsramme: 4-6 weeks gestation

Cumulative clinical pregnancy from cycles initiated within 6 months post randomization is assessed at 4-6 weeks gestation. Cumulative clinical pregnancy is determined using the cumulative outcome of up to the first two embryo transfers. Subjects with a gestational sac visualized with TVU are considered as having achieved a clinical pregnancy. Clinical pregnancy is recorded as either a Yes or No for each of the Subject's transfer cycles. Subjects without a clinical pregnancy assessment are considered as a No unless a later observation indicates otherwise (i.e., an ongoing pregnancy or live birth). Cumulative clinical pregnancy is derived as either a Yes, if at least one of the first two embryo transfers achieves a clinical pregnancy, or a No otherwise.

4-6 weeks gestation
Cumulative live birth.
Tidsramme: Greater than 24 weeks gestation

Cumulative live birth from cycles initiated within 6 months post-randomization. Live birth is confirmed at >24 weeks gestation by the presence of signs of life such as breathing, heartbeat, pulsation of the umbilical cord, or definitive movement of voluntary muscles. Cumulative live birth is determined using the cumulative outcome of up to the first two embryo transfers. Subjects with at least one neonate meeting the definition of live birth are considered as having achieved a live birth. Live birth is recorded as either a Yes or No for each of the Subject's transfer cycles. Subjects without a live birth assessment are considered as a No. Cumulative live birth is derived as either a Yes, if at least one of the first two embryo transfers achieves a live birth, or a No otherwise.
